Anemia hemolítica por deficiência de piruvato cinase dos eritrócitos
ORPHA:766CID-10 · D55.2CID-11 · 3A10.YOMIM 266200DOENÇA RARA

Um distúrbio metabólico genético raro, causado pela falta de uma enzima chamada piruvato quinase. É caracterizado por um tipo de anemia crônica (de longa duração) com diferentes níveis de gravidade, em que os glóbulos vermelhos são destruídos, mas sem adquirir um formato esférico anormal. Isso causa sintomas que podem variar bastante, desde casos de anemia grave, que podem ser fatais logo após o nascimento, até situações onde a destruição dos glóbulos vermelhos é tão bem compensada pelo corpo que a pessoa não apresenta sinais visíveis de anemia.

Pyruvate kinase deficiency modifies sickle hemoglobin carrier and sickle cell disease phenotypes in mice.

JCI insight2026 Feb 23

Growing evidence indicates that PKLR, the gene for pyruvate kinase (PK), is a genetic modifier of the sickle cell phenotype. Coinheritance of specific PKLR variants is associated with increased pain-related hospitalization and can trigger sickle cell disease (SCD) phenotypes in asymptomatic carriers. PK deficiency disrupts RBC glycolysis, leading to ATP deficits and accumulation of 2,3-diphosphoglycerate, which exacerbates sickling in SCD. Using CRISPR-Cas9, we generated null mutations in Pklr [Pklr(13ntdel/13ntdel) or Pklr(246ntdel/246ntdel)] specific for the RBC isoform (PKR) in Townes mice that were homozygous (SS) or heterozygous (AS) for the human sickle globin gene, or homozygous for human hemoglobin A (AA, controls), to investigate the effect of PKR deficiency on the sickle phenotype in mice. PKR-deficient AA and AS mice developed severe anemia, reticulocytosis, and substantial spleen and liver iron deposits. Unlike what is observed in humans, PKR deficiency in AS and SS mice surprisingly decreased sickling, but it was also associated with increased extramedullary hematopoiesis and mitochondrial retention in mature RBCs. These results demonstrate the differential effect of Pklr mutations on the phenotype of both AS and SS mouse models, offering insights into the complex role of PKR deficiency in SCD pathology.

Pyruvate Kinase Deficiency: Markedly Decreased Reticulocyte PK Activity and Limited Specificity of the PK/HK Ratio.

International journal of molecular sciences2025 Sep 04

Diagnosis of pyruvate kinase deficiency (PKD) remains challenging in clinical practice. The pyruvate kinase (PK) to hexokinase (HK) activity ratio (PK/HK) was proposed to reduce the confounding effect of reticulocytosis on PK activity measurement. However, decreased PK activity and PK/HK ratios have also been observed in other anemias, raising doubts about their diagnostic value. We assessed the diagnostic accuracy of PK/HK ratio versus PK activity in differentiating PKD from other hereditary anemias. This study included 41 patients with molecularly confirmed PKD and 62 patients with other anemias. We also evaluated the influence of reticulocytosis and transfusions on erythrocyte PK activity. The PK/HK ratio showed 73% specificity, while PK activity alone achieved 95%. In PKD patients, reticulocytosis did not affect PK activity because reticulocyte PK activity was already markedly reduced (23-fold) compared with controls. In other anemias, decreases in PK activity were present in both reticulocytes and erythrocytes, but to a lesser extent. Transfusions contribute more to the false-normal result of PK activity than reticulocytosis. Measuring reticulocyte-specific PK activity during regular transfusions provided reliable results, as only patient-derived reticulocytes are present in the blood. PK activity demonstrates higher specificity than PK/HK ratio in diagnosing PKD. Reticulocytosis is not a confounder, while transfusions remain the main limitation. Reticulocyte-specific PK activity measurement may improve diagnostic accuracy in transfused patients.

Hereditary disorders of ineffective erythropoiesis.

Blood cells, molecules &amp; diseases2025 Mar

Under steady state conditions, humans must produce ∼2 million red blood cells per second to sustain normal red blood cell counts and hemoglobin levels. Ineffective erythropoiesis, also termed dyserythropoiesis, is a process by which erythroid precursors die or fail to efficiently differentiate in the bone marrow. Ineffective erythropoiesis is characterized by expanded bone marrow erythropoiesis and increased erythroferrone production by bone marrow erythroblasts, with the latter resulting in reduced hepcidin production and increased iron absorption. Ineffective erythropoiesis may result from acquired and congenital conditions. Inherited causes of ineffective erythropoiesis include β-thalassemia, sideroblastic anemias, pyruvate kinase deficiency, and congenital dyserythropoietic anemias. This manuscript reviews the definition and evidence for ineffective erythropoiesis and describes the most common hereditary disorders of dyserythropoiesis.

Mitapivat for Acquired Pyruvate Kinase Deficiency.

Pediatric blood &amp; cancer2025 Feb

Pyruvate kinase (PK) activation is emerging as a promising treatment modality for numerous congenital hemolytic anemias of diverse pathophysiology, and one agent, mitapivat, is already licensed to treat patients with congenital PK deficiency. However, PK deficiency may also be acquired in the setting of clonal myeloid disorders and other pathologies, where it may result in severe hemolytic anemia and remains without known therapies. This case report describes the novel application of mitapivat therapy in a patient with acquired PK deficiency causing red cell transfusion dependence, liberating the patient from transfusions and resulting in marked improvement in symptoms and quality of life.

Metabolic Rigidity as a Mechanical Barrier to Malaria: Flickering Loss in PKLR-Deficient Erythrocytes.

FASEB journal : official publication of the Federation of American Societies for Experimental Biology2025 Nov 30

Pyruvate kinase (PK) deficiency is a rare hereditary enzymopathy caused by mutations in the PKLR gene, leading to reduced glycolytic ATP production in red blood cells (RBCs) and contributing to chronic hemolytic anemia. Here, we use high-speed flickering spectroscopy and non-invasive microrheology to assess how ATP depletion reshapes the nanomechanical properties of RBC membranes. Compared to healthy controls, PKLR-mutant erythrocytes exhibit marked reductions in ATP-dependent flickering amplitude and membrane fluidity, consistent with impaired metabolic elasticity. Strikingly, when infected with Plasmodium yoelii, these metabolically rigidified cells retain mechanical properties that appear to hinder parasite-induced membrane remodeling. By mapping single-cell viscoelastic landscapes across healthy, mutated, infected, and coinfected mouse RBC populations, we uncover a potential biomechanical barrier against malaria imposed by glycolytic insufficiency. These findings highlight a mechanobiological axis of host resistance and position label-free flickering analysis as a powerful tool for diagnosing RBC enzymopathies and probing infection susceptibility at the single-cell level.
